Xylem transports only inorganic nutrients while phloem transports only organic materials.

Xylem help in the transport of

The hormones which regulate phloem transport are

Statement 1: Xylem transport is unidirectional. Statement 2: Phloem transport is bi-directional.

Element required for phloem transport is

Define the following: Source and sink in phloem transport

Explain why xylem transport is unidirectional and phloem transport bi-directional,

Explain why xylem transport is unidirectional and phloem transport bi-directional.

[A]: Xylem transports sap from root to shoot. [R]: Phloem translocates food.

How many of the following statements are not correct? [I] In a flowering plant the substances that would need to be transported are water, mineral nutrients, organic nutrients and plant growth regulators. [II] Over small distances, substances move by diffusion and by cytoplasmic streaming supplemented only by passive transport. [III] Organic and mineral nutrients undergo multidirectional transport through the xylem. [IV] From the storage organs, organic compounds are later re-exported. [V] Phytohormones and other chemical signals are transported to maintain and regulate the plant functions.

Osmotic pressure at sink decreases in phloem transport because
